Though the Tokyo Olympic Games drew to a close on August 8, 2021, the public is still watching the athletes. Their outfits and the technologies that helped them in the competition have aroused people's interest.
Su Bingtian, the first Chinese sprinter to reach an Olympic 100m final, has ascribed his breakthrough to scientific training. "It takes Su 47 steps to run 100 meters. Each step counts, " Liang Dong, a member of Su's training team, told Shenzhen Evening News. "Randy Huntington, Su's American coach and a biomechanics expert in track and field, has collected a lot of data on
outstanding sprinters and built a database. He put in all of Su's data and got a near-optimal model. When Su is training, the team uses high-speed cameras to record his training and compares it with the model to find out his weaknesses. "Technology has also brought a new boost to table tennis. On July 27, the semifinal match between China's Sun Yingsha and Japan's Mima Ito was in full swing at the Tokyo Metropolitan Gymnasium. You wouldn't have guessed that besides players, referees and audiences, a powerful AI platform was monitoring the match.
Every serve, swing and movement of Mima Ito was captured by this AI cloud platform deployed in Tokyo. At an average speed of 100 Mbps, the data was transmitted to the technical team of the Zhejiang University Table Tennis Intelligent Big Data Analysis Platform, 2, 442 kilometers away from the Tokyo Metropolitan Gymnasium, according to The Paper.
The Tokyo Olympic Games have seen not only scientific support in training, but many high-end technologies in athletes' devices. For example, the Kenya women's volleyball team's GPS devices fed data on each player's strength, heart rate and so on to coaches, who used the information to prevent injury and personalize training plans for each individual, South China Morning Post reported.
Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing?Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.
"I would never have said to my mom, 'Hey, the new Maroon 5 album is really great. How do you like it?"" says Ballmer. "There was just a complete gap in taste. " Music was not the only gulf. From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.
Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of mutual trust and friendship that can continue into adulthood. But family experts warn that the new equality can also result in less respect for parents. "There's still a lot of strictness and authority on the part of parents out there, but there is a change happening, "
says Kerrie, a psychology professor at Lebanon Valley College. "In the middle of that change, there is a lot of confusion among parents. "
Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic (民主的） process that encourages everyone to have a say.
"My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side. " explains Mr. Ballmer. "It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now. "
Losing your ability to think and remember is pretty scary. We know the risk of dementia (痴呆 症） increases with age. But if you have memory slips, you probably needn't worry. There are pretty clear differences between signs of dementia and age-related memory loss.
After age 50, it's quite common to have trouble remembering the names of people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women's Hospital in Boston.
The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.
Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don't remember even seeing it, that's far more concerning, Daffner says.
When you forget entire experiences, he says, that's "a red flag that something more serious may be involved. " Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you've visited many times before can also be signs of something going wrong. But even then, Daffner says, people shouldn't panic. There are many things that can cause
confusion and memory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications like antidepressants. You don't have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defenceagainst memory loss is to try to prevent it by building up your brain's cognitive (认知的） reserve, Daffner says.
"Read books, go to movies, take on new hobbies or activities that force one to think in novel ways, " he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a known brain promotion.
Shyness is normal and it is not considered as a mental problem. All people have been shy at one time or another. Even the most confident people experienced being shy. . You probably are wondering why you are shy. It may be because of the environment you were used to or the way you were brought up. Certain events or incidents in the past may also lead to the reason why you are shy now. Most shy people have shy parents and relatives and it is not surprising to find out that they too have become shy persons. One of the negative sides of being shy is having the tendency to be passive. Most of the time shy people can't stand up for themselves and what they believe is right. This apparently influences their social life as well as work, family and other aspects of their life.
While shyness has negative aspects, it has positive sides. Shy people are usually good observers and do not get themselves into too much trouble because they try to observe their environment or any situation before they act. They can also make great friends. Since they have difficulties in social scenes, making friends seems to be a must. Therefore, they value their friends wholeheartedly and have proven to be loyal and thoughtful friends. Some of them born with shy parents have successfully battled against being shy. This contributes to their constant self-improvement, developing self-esteem and trying to be exposed to new environments.
A. But in most cases, shyness proves to be genetic.
B. They are sensitive and accustomed to getting suspicious.
C. Because some people are born to be shy, they let it go hang.
D. So if you're feeling shy, don't worry because you are not alone.
E. They are not hot-headed and think twice before making any decisions.
F Although shyness is something from birth, it can be improved over time.
G. They avoid crowds by nature and stay away from groups and social interactions.
Jinghong is a city in Southwest China's Yunnan Province. The city will soon open a food source1especially developed for Asian elephants, in an effort to reduce2between humans and the animal.
The project with investment of 1 million yuan ($154, 686), 3in December and was completed in May. The base, which 4three townships across 67 hectares, has grown some of the elephants' favorite 5including 38, 000 musa basjoo trees, a species of banana. Construction workers also built several ponds and 62 metric tons of salt to meet the elephants' mineral 7.
"The project is meant to improve the quality of Asian elephants' habitat, enrich their food sources and provide them with more to 8 "said Cha Wei, an official from the bureau, " After the 9of the project, elephants will be able to eat in the food source base, which can stop them from foraging (觅食） in 10and damaging farmers' crops." Obviously, the increasing number of Asian elephants is closely linked to the growing awareness of people to protect11
Cha explained that elephants are very12and understanding of each other. When their population reaches a certain number, a herd will 13to reduce crowding and14interbreeding (异种交配）. "The elephants' trek (长途跋涉） earlier this year also 15the rising number of herds" Cha said, 16a herd of 15 elephants that17their habitat in Xishuangbanna and started migrating (迁徙） north in March last year, with their 18attracting global attention. 19ongoing wildlife protection efforts, the number of wild Asian elephants in the province has increased from 170 in 1980 to 300 today. Jinghong is home to about 185 elephants, and their habitat 20into about 350, 000 hectares.
UBC Professor Simard explains how trees are much (complex) than most of us ever imagined.
Although Charles Darwin (think) that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, opposite is true: trees survive through their co-operation and support, passing around necessary nutrition "depending on who needs it".
Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount (keep) them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree (destroy), it affects all. Simard talks about "mother trees", usually the largest and oldest plants on all other trees depend. She explains how dying trees pass on the wealth to the next generation, (transport) important minerals to young trees so they may continue to grow. When humans cut "mother trees" with no awareness of these highly complex "tree societies" the networks on which they feed, we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it, " Simard says sadly, If we could put across the message to the forestry industry, we could make a huge difference to our (environment) protection efforts for the future.
Maybe we all live in each other'spaces. Perhaps this is what the photo I took during a summer holiday is for. if you treat others with patience and tolerance, then you'll likely be repaid in another space.
Fifteen years ago, I took a trip in Lecce in southern Italy that summer. Lecce is an important stage for art and culture lovers. Walking in the city center is a dive into the past, between churches and antique buildings that keep precious details and decorations. More importantly, it's an ideal place for
photographers. One morning, I got up early enough for a panoramic (全景的） view of the sunrise, the blue sea, white buildings and green olive trees. After climbing up a hill, I paused to catch my breath and then positioned myself to take the best photo of this panorama.
Unluckily, I was about to take out my camera when suddenly a woman approached from behind, and planted herself right in front of my view. Like me, I thought, this woman was here to stop for a short rest, and enjoy the scenery. Beyond my expectation, she stood still as if something caught her
eye, not noticing anyone else's presence around her. Patient as I was, after about 10 minutes, with my camera scanning the sun and reviewing the shot
I would eventually take, I got bored. Was it too much to ask her to move aside so that I could take just one picture of the landscape? Of course, I could have asked her, but something prevented me from doing so. She seemed so content in her observation that I didn't have the heart to mess with that.
Another 10 minutes passed. However, the woman was still there. I grew frustrated. I decided to take the photo anyway. With an unwilling touch of the shutter, I left in low spirits.
